Description of LQ3568 core board independently developed by Luoshiqi Technology:
1. It integrates GPU, VPU, and NPU co-processing, and has strong video coding and decoding capabilities, which can be switched in one-click among DC architecture models such as Caffe/TesorFlow;
2. Luoshiqi 3568 core board adopts dual-channel LPDDR4 design, the main frequency is up to 1.5GHz, with low cost and high cost performance;
3. The number of pins is as high as 200pin, which brings out almost all the functional characteristics of the CPU, which is convenient for customers to develop;
4. The size is only 55.8mm*55.8mm, with large expandable space;
5. Support dual Gigabit Ethernet, WiFi6, USB3.0, SATA, etc., with complete functions;
6. The core board has undergone a large number of drop tests, high and low temperature tests, aging tests, stable performance, and the baking machine runs normally for 7 days * 24 hours.
